- FIG. 4 is a representative flowchart for a variation of the FIG. 3 method.
- FIG. 1 Representatively illustrated in FIG. 1 is a system 10 for use with a well, and an associated method, which can embody principles of this disclosure.
- system 10 and method are merely one example of an application of the principles of this disclosure in practice, and a wide variety of other examples are possible. Therefore, the scope of this disclosure is not limited at all to the details of the system 10 and method described herein and/or depicted in the drawings.
- a well tool 12 is connected as part of a tubular string 14 installed in a wellbore 16.
- the wellbore 16 is lined with cement 18 and casing 20, but in other examples the wellbore could be uncased or open hole.
- the well tool 12 could in some examples be conveyed by wireline, slickline, a downhole tractor, or any other type of
- the well tool 12 could be positioned at or near the earth's surface or a subsea location.
- the well tool 12 could be an insert, outsert or sonde.
- the well tool 12 may be removed from, or installed in, another well tool.
- the well tool 12 could be installed in a marine riser, in a subsea wellhead, in an earth
- the well tool 12 may be any type of well tool.
- the well tool 12 could comprise a valve, a packer, a well testing tool, a fluid sampler, a formation tester, a logging tool, a perforating tool, a running tool, a
- FIG. 2 an enlarged scale representative cross-sectional view of one example of the well tool 12 is representatively illustrated.
- the well tool 12 includes an internal chamber 24 in which an electronic printed circuit assembly 26 is disposed.
- seals 28 are provided in the well tool 12.
- the seals 28 could be of the type known as o-rings, but other types of seals may be used, if desired.
- a flow passage may conduct well fluids through the well tool 12. It may be desired to isolate the chamber 24 from such well fluids and pressures.
- seals 28 be used to isolate the chamber 24 from well fluids and pressures.
- welds, threads or any other type of pressure isolating devices may be used instead of, or in addition to, the seals 28.
- a chamber 24 it is not necessary for a chamber 24 to be isolated from well fluids and pressures, in keeping with the scope of this disclosure. For example, characteristics of
- a pressure sensor 30 is positioned in the chamber 24.
- the sensor 30 is mounted to the printed circuit assembly 26, but the scope of this disclosure is not limited to any particular mounting position for the sensor.
- sensors 30, and any number of chambers 24 There may be any number of sensors 30 per chamber 24.
- the well tool 12 After the well tool 12 is assembled, it is pressure tested prior to being installed in the well. However, instead of applying external pressure to the well tool 12 (e.g., to at least partially simulate well conditions), pressure is applied internally to the chamber 24.
- the pressure applied to the chamber 24 could be positive or negative pressure (relative to atmospheric pressure).
- a positive or negative pressure of about 2-3 bars could be applied to the chamber 24 at a surface location (such as, a land well site, a floating rig, a jack- up rig, a workshop, etc.) via a port 32.
- a fluid used to pressurize the chamber 24 could comprise air, nitrogen, another inert gas, etc.

If the sensor 30 detects a loss of pressure (e.g., in the case of positive pressure being applied to the chamber) or a gain of pressure (e.g., in the case of negative pressure being applied to the chamber), this can be used as an indication of leakage from the chamber 24.

- a pressure differential will be created across each of the seals 28 in one direction (e.g., outward from the chamber to the exterior of the well tool 12, or inward from the chamber to the interior of the well tool).
- pressure will be applied exteriorly and/or

Any pressure change detected by the sensor 30 (other than that due to temperature fluctuations, etc.) can indicate a potential problem with the well tool 12.
- Multiple sensors 30 could detect pressure at multiple respective different locations (e.g., in different chambers 24 or pressure zones, between seals 28, between a seal and a backup ring, etc.).
- the pressure test described above does not necessarily duplicate well conditions, but the test is sufficient to detect certain defects, such as, missing, damaged, worn, aged or improperly installed seals 28, cracks in pressure bearing housings or welds, leakage past threads, etc.
- the pressure test does not require use of bulky and expensive external pressure test chambers, high pressure pumps, control systems, safety enclosures, etc.
- the well tool 12 can be installed in the well, with the pressure sensor 30 remaining in the chamber 24. In this manner, the sensor 30 can continue to monitor pressure in the chamber 24 while the well tool 12 is in the well.
- a pressure increase detected by the sensor 30 while the well tool 12 is in the well can indicate an impending failure of the well tool due to well fluids entering the chamber 24. If the chamber 24 is used
- the senor 30 can be used for monitoring the pressure level in the chamber as the well tool 12 is operated in the well. A pressure decrease detected by the sensor 30 can indicate leakage from the fluid pressure storage .
- the printed circuit assembly 26 may be surrounded by a fluid, so that the chamber 24 can

- the pressure sensor 30 is embedded in the chamber 24 in step 36 .
- the sensor 30 is mounted to the printed circuit assembly 26 , but other techniques for positioning or mounting the sensor in the chamber 24 may be used, if desired.
- the chamber 24 is internally pressurized.
- a pressure of only about 2 -3 bars is applied to the chamber 24 .
- a source of pressure may be chosen because of its convenience to a rig, work facility, etc.
- a relatively low pressure may be chosen, so that safety risks are minimized, but leakage from the chamber 24 can still be detected by the sensor 30 .
- the scope of this disclosure is not limited to any particular positive or negative pressure or level of
- step 40 the chamber 24 pressure is monitored using the sensor 30 .
- the sensor 30 is conveniently mounted to the printed circuit assembly 26 for supplying electrical power to the sensor, and for transmitting
- measurements from the sensor e.g., via wired or wireless means, via optical waveguide, radio frequency identification (RFID), acoustic means, etc.
- RFID radio frequency identification
- acoustic means etc.
- the scope of this disclosure is not limited to any particular way of supplying electrical power to the sensor 30 , or of transmitting measurements from the sensor.

- the well tool 12 may be conveyed into the wellbore 16 by any type of conveyance (or no
- FIG. 4 Another example of the method 34 is representatively illustrated in flowchart form in FIG. 4 .
- the steps 40 , 42 are reversed, so that the chamber 24
- pressure is monitored using the sensor 30 after the well tool 12 is installed in the well.
- This order of steps may be desired to detect leakage into or out of the chamber 24 , or any other type of pressure change or lack of change in the chamber, while the well tool 12 is in the well.
- the sensor 30 may be used to monitor pressure in a pressurized gas chamber, to verify functionality of a liquid spring, to detect impending failure of the well tool 12 , etc.
